摘要: 为了使光纤激光在线选择整形金刚石砂轮达到理想的整形精度，采用计算机、CCD传感器、PCIe-6361型数据采集卡为主要硬件，LabVIEW作为上位机软件开发工具搭建了一套光纤激光在线整形金刚石砂轮系统。该系统不仅可以实现金刚石砂轮的激光在线整形，而且可以在短时间内实现对砂轮表面轮廓的高精度测量和数据存储。结果表明，通过对砂轮的轮廓测量，设定金刚石砂轮的整形阈值为38.23m，采用功率35W、重复频率50kHz的光纤激光整形金刚石砂轮，整形后砂轮高点的高度值基本上控制在38m以下。该系统设计能满足金刚石砂轮的整形要求。Abstract: In order to realize the desired shaping precision of fiber laser online-selective shaping diamond wheel, a fiber laser online shaping diamond wheel system was built by utilizing the computer, charge coupled device(CCD) sensor, PCIe-6361 data acquisition card as the main hardwares and LabVIEW software as the computer development tools. The system can not only realize diamond wheel shaping with laser on line, but also achieve high precision measurement on the surface profile of the grinding wheel and data storage in a short time. Experimental results show that, after the measurement of wheel contour, when the system of fiber laser shaping diamond grinding wheel is set with diamond wheel shaping threshold of 38.23m, power of 35W, repetition frequency of 50kHz, the maximum height of wheel after shaping is under 38m. The system design can meet the shaping requirements of diamond wheel.
